XVIII IMEKO WORLD CONGRESS Metrology for a Sustainable Development September, 17–22, 2006, Rio de Janeiro, Brazil ULTRASOUND MICROSCOPY TECHNIQUES TO DETECT DELAMINATION IN STACKED LAYERS

چکیده
We present the theory and some applications of the synthetic aperture focusing technique applied to single transducer ultrasonic data sets. In this technique a virtual source located at the geometrical focal point of the physical transducer is algorithmically generated and thus allows for tighter focusing over a geometrically larger scan volume. We present results from a structural test phantom (two copper wires) and a delaminated specimen.

We present here expressions to determine the uncertainty interval of the estimates of transition voltages and code bin widths of an analogue to digital converter obtained with the Standard Histogram Test. We consider the presence of additive noise as it influences the precision and causes a bias on the test results.

The main purpose of this paper is to present a possibility theory-based generalization of conventional interval propagation to coverage intervals. Indeed, the whole set of coverage intervals for all the probability levels stacked on top of one another constitutes a possibility distribution. Thus by slight modifications of Zadeh’s extension principle, we will prove that it is possible to compute...

This paper presents a microsystem for biomolecular recognition (DNA, enzymes) based on a biochip, which uses magnetic field arraying of magnetically tagged biomolecules and high sensitivity sensors for single biomolecule detection. The microsystem provides the electronic circuitry for addressing, reading out and sensing each of the 16× 16 magnetoresistive sensors that compose the biochip. A pro...

In the paper, two approaches to measurements of circuit functions of analog parts of mixed-signal systems controlled by microcontrollers are presented. They base on the utilization of internal resources of the microcontrollers. The first approach uses an analog to digital converter (ADC), an analog comparator and a timer. The second one uses only the ADC and the timer. The measurement procedure...
